My answer won't be very enlightening but here it goes: "I hope so" :).
I do think that in the far future this could be possible, although it is not going to be easy because different tissues in the body regenerate differently and their regeneration speed differs a lot as well. For example skin tissue regenerates quite fast and every 28 days you have a compeltely new skin. Cardiomyocyte heart cells though regenerate fairly slow, only 1% is replaced a year.So probably it won't be possible to "invent" something that makes the whole body regenerate faster, because of the different ways in which tissues work.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
